Direct Reduction of Nickel Laterites

Malachite Consulting has undertaken testwork and engineering studies for the direct reduction of iron and nickel, from nickel laterites, in order to produce a high value product for sale.

The process typically involves reducing the metal oxides in a rotary kiln, followed by cooling of the reduced product. The cooled product is then crushed and upgraded using magnetic separation, to remove the gangue material. Depending on the shipping and customer requirements, the final product is cold briquetted to reduce dusting losses and to facilitate handling.
